Datepicker For Bootstrap Does Not Work In Modal Window

I have issue with bootstrap datepicker, I use this plugin, because Disabling dates in the past and dependent disabling. Whether the problem could be because I use twice on the sam

Solution 1:

I take a few a hour to put this to work but finally I solved.

.bootstrap-datetimepicker-widget {
  z-index:10800!important;
  display: block;
}

Solution 2:

add css .datepicker {z-index: 1151 !important;}
